Matshita uj-840d


Hi, usually and error code in device manager means a sofware conflict with the device. You can try deleting the lower and upper filters in the registry if you feel comfortable. Here are the steps:
1) Close all open programs
2) Click on Start, Run, and type REGEDIT and press Enter
3) Click on the plus signs (+) next to the following folders

* HKEY_LOCAL_MACHINE
* SYSTEM
* CurrentControlSet
* Control
* Class
* {4D36E965-E325-11CE-
BFC1-08002BE10318}

4) This folder is the DVD/CD-ROM Drive Class Description in the registry. Look for any of the following names in the right hand column.

* UpperFilters
* LowerFilters
* UpperFilters.bak
* LowerFilters.bak

5) If any of the above keys shown in step 4 are listed, right-click on them and choose Delete
6) After deleting the keys, close the Registry Editor
7) Reboot your computer

Purito

I think you have to run this Microsoft tool

At the HP site you will also find information and a patch to solve the problem.

My Matshita UJ-840D DVD/CD-ROM Drive Stopped working


Hi,
i,m assuming this is A laptop Computer ?
The only thing you can try is this:-
go to My Computer/Control Panel/ System/Device Manager.
see if there are any yellow triangles or exclamation marks by your problem device. if so click un-install. then at the top of that page, there is a refresh icon or similar. which will rescan the systems bus.
failing this try add new hardware wizard, in control panel.
finally ensure the device is connected correctly, unlock/remove and re-insert. update any device drivers for this.

MATSHITA UJ-840D, has disappeared and I can't play cd's/dvd's.


Before you do this though export your current registry to the desktop by selecting export from the file menu. If this doesn’t work just double click on the exported on to restore it.

1. Start Registry Editor by typing regedit into the start search box in the bottom left hand corner of the start menu.
2. In Registry Editor, expand Computer, and then expand HKEY_LOCAL_MACHINE.
3. Expand SYSTEM, and then expand CurrentControlSet.
4. Expand Control, and then expand Class.
5. Under Class, click {4D36E965-E325-11CE-BFC1-08002BE10318}.
6. In the details pane of Registry Editor, on the right side, click UpperFilters.
7. Right click and select delete
8. Click Yes when you receive the following message: Are you sure you want to delete this value?
9. Now look for LowerFilters in the right hand panel.
10. Right click and select delete
11. Click Yes when you receive the following message: Are you sure you want to delete this value?
12. Exit Registry Editor
13. Restart the machine
It wit worked for me on Acer with UJ845D XP Good luck
